Hi Sir,
It works normally when just only one camera opened like below.
Camera mcamera = Camera.open(0);
or
Camera mcamera = Camera.open(1);
both the stream video are also ok to display.
BUT I try open two cameras to preview at the same time in Android APP.
it always crashed and seems like framework issue. Please help me out,
Many thanks!
